Abstract
A lie board used for fitting golf clubs to golfers having a crested portion. In one embodiment the upper surface of the lie board is curved convexly with respect to the lower surface of the lie board. The crested portion can include the entire lie board, or only the portion where contact between the sole of the club and the board is anticipated. The crested portion can have curvature in only a single direction, or it can be curved in orthogonal directions to produce an essentially dome-shaped lie board. When only a single direction of curvature is used, the curvature is preferably in the intended general direction of the travel of the club head across the lie board.

The invention relates to a method for producing golf clubs that are individually adapted to the respective height of golf players. According to the invention, a test person firstly executes, with a test club whose distance from the floor (H) corresponds to the distance of the wrist of the upright-standing test person from the floor, one or more test strokes on a specially prepared flat base. Afterwards, the line of contact of the bottom (5) of the test club head (1) with the base is determined, and the distance of the line of contact from the club head central plane (0) is measured. The length (L) of the shaft (2) is subsequently adapted according to this measured distance. The invention also relates to a template and a chart.
